Figure F30. Correlation diagrams of (A) deep vs. medium resistivity, (B) deep vs. shallow resistivity, (C) ring vs. bit resistivity, and (D) deep vs. ring resistivity. On each plot, the black line is the line of unit slope passing through the origin and the red line is the linear fit to the data. Equations describe the least-squares regression curves and R is the correlation coefficient.
